We have done both and enjoyed both. Not sure why someone would say that JUTA doesn't stop for bathroom breaks and to get an ice cold red stripe. We always stop with JUTA....every time. We always had a blast laughing and talking to the other passengers on the bus! It was a fun ride and was nice meeting new people.
If you want a private ride I want to recommend shane. He took really good care of us and he was very reasonable. he has a nice facebook page....Shane Taxi.
